If the criterium is solely "Is its output sufficient to do X," you could easily have a job meet that criterium for all three Roles, especially with the way things have been going of late.
That's true, but that's where game balance comes into play. You could design a job that does all 3 things competitively, but that isn't exactly healthy to the balance of a game. Regardless of how they engage with DPS, both healers and tanks should not deal as much damage as DPS jobs, because if they did, then why bring a frail DPS that cannot sustain themselves when you could bring a tank who deals as much damage but also has considerably greater survivability or a healer who deals as much damage but provides significant levels of sustain to the entire party?

There does need to be balance, but rules like "Can only have X amount of DPS actions per healing actions" are arbitrary. Why does it matter so long as you can do the job your role is responsible for competitively with the other jobs of the same role? And it's not like I'm trying to advocate for a job that just has one 400 potency AoE regen that lasts 60 seconds and is otherwise all DPS focused, or anything extreme. I just think the potential outlook of looking at a job and saying "Mmmm... No. You have 1 DPS cooldown too many, you're not a healer" is ridiculous.
